WILLIAM R. GODFREY, OF SIDNEY, NEBRASKA.

ADJUSTABLE WRENCH.

SPECIFIGATI ION forming part of Letters Patent No. 254,210, dated February 28, 1882. Application filed August 19, 1881. (MbdeL) To all whom it may concern Be it known that I, WILLIAM R. GODFREY, of Sidney, in the county of Cheyenne and State of Nebraska, have invented a new and useful Adjustable Wrench, of which the following is a specification.

My invention relates to. improvements in wrenches for removing or setting up nuts upon bolts, to be used in conjunction with a bitbrace.

The objects of my improvement are, first, to provide an adjustable wrench to be used upon all sizes of nuts desired; second, to provide a perfect attachment for a bit-stock or bit-brace, and combine the two to form a complete, rapidly-adjustable, and cheap wrench; third, to furnish a rapid-acting wrench which can be used to reach into intricate and sniall places, where an ordinary wrench cannot be used. I

attain these objects by the mechanism illus-' trated by the accompanying drawings, in which'- Figure 1 is a vertical longitudinal sectional view. Fig.2 is a side view of the device with the jaws and adjusting-nut removed. Fig. 3 is a perspective view of the nut. Fig. 4 isa transverse sectional view on the line y y, Fig. l; and Fig. 5 is atransverse sectional view on the line as m, Fig. 2.

Corresponding parts in the several figures are denoted by the same letters of reference.

In the drawings, A designates the main stem or shank, having screw-threaded portion E, which is slotted centrally, as shown at 0, thus forming two parallel nearly semicircular long arms, 6 6, between which in the slot 0 are pivoted the wrench-jaws B B by means of transverse pin D. The jaws B B are formed with flanges a at their center,which flanges overlap each other and by means of which the jaws are pivoted together. The jaws are beveled at their tops I), so that when in their normal position they will embrace the V-shaped portion 6 of the shank E,and thus form a smooth circular upper portion. Odenotes anutscrewthreaded on its inside 0, which is adjusted round the screw-threaded portion E over the jaws, and by operating which the latter may be readily expanded or contracted to fit and tightly clasp different sizes of nuts.

Byreference to'the above description, taken in'connection with the drawings hereto annexed, the operation and advantages of my invention will be readily understood. It is simple, convenient, durable, easily operated, and efficient for the purpose for which it was designed.

I am aware that prior to my invention wrenches have been made with a stem or shank to attach to bit-braces; but such shankor stem was furnished with a solid square opening, and as many shanks were needed as would be required to turn all the different-sized nuts in use. I do not therefore claim the shank as used in a bitbrace as a new invention but What I do claim as myinve'ntion, and desire to secure by Letters Patent, is

As an improvement in wrenches, the combination,with the shank A, provided with straight screw-threaded portion E, having a central longitudinal slot, 6, and a V-shaped portion, 6, of the jaws B 'B, pivoted in said slot and having their tops beveled to fit said V-shaped portion, and the single adjustinguut 0, arranged around portion E, substantially as and for the) purpose herein shown and specified.
